IMPROVEMENT IN DRAIN-PIPE MACHINES.

The Schedule referred to4 in these Letters Patent and making part of the same.

ToJill whom it may concern:

Be it known that I, ISAAC C. BRYANT, of the city of \\"asliington, District ot' Columbia,have invented an Improved Machine for Making Drainage-Pipes, Curb, and Gutter-Pieces; and I do hereby declare the following to be an exact description thereof, ret'- ereuce being had to the accompanying` drawings, and to the letters ot' reference marked thereon, making a part ot' this speciticatimi, iii which--V Figure 1 represents a vertical and sectional elevation o'f lthe machine.

Figure'tl, a view of the upper side of the monti-1- piece.

Figure?, is a. view of the upper side ofthe mouthpiece, for forming pipes et' various sizes, at one'operation.

Figure 4, the four mouth-pieces combined, for forming four pipes at one operation.

Figure 5, the under-side view of the mouth-piece, for f brming gutter-pieces.

Figure 6, the under-side view of the mouth-piece, for tbl-ming curb and gutter pieces in one piece.

The nature of my invention consists in the peculiar arrangement otl the vertical conical clay-hopper, with its iia-uged screw above, conical grooved screw below, and cylinder surrounding the core forming the mouthpiece, the mouth-piece being so constructed wit-l1 two or more cylinders, so as to form two or more' different sizes of pipe at one operation, or t'our cylinders, with their cores set square, so as to form four pipes of the same size, or of dii-ferent sizes, as required; also, a single cylinder, with its inside core and tlange across the inside ot' the cylinder, to ferm t\\'ogutterpieees at one operation; also, a pattern, with the shape of a curb and gutter-piece, so constructed as to form the curb-stone and gutter-piece in one pressure or mould` `ing. Y v

The obieetof my invention being to cut and feed the clay in the hopper by means ot' the iianged screw above, to the. grooved screw' below, and the winged" pieces below the flanged screw are i'or the purpose of checking the clay, to prevent it iiom revolving with thesrrew, and iorcing the clay to the mouth ot' the lower grooved screw, while the two side flanges, on the'inside ot' the hopper, also prevent the clay from revolving with-the screw.

'lhe'object ot' the lower grooved screw-is to force the cla-y down into the cylindrical moulds to form the pipe or curb and gutter-pieces.-

A represents the upright frame that supports the devices.

l, the double bevel-gearing at top, to operate the main spindle C, with itstianged screw D, and grooved screw E, inside of the clay-hopper G, that is tapering, wide at top and narrow at the bottom.

The clay is thrown into the hopper at the top, when the revolving ianged'screw D forces the clay down to the Lower grooved screw E, Iwhile the side ianges H, and the lower angular' winged auges I, prevent the clay from revolving with the screw D, and assist in forcing the clay down to the lower screw E, the spindle C resting and being supported by the cross-piece ot fraaie A, at top, and at the centre of the crosslanges I.

The lower screw E is tapering,to correspond with the inside of the lower end ot' the hopper G, fitting closely at the top tothe ring K in the hopper G, so that ,the clay cannot force upward, and the two lower side ilanges L L are for the purpose of preventing the clay from revolving with the lower screw E. The clay being then forced down to the cylindrical mouthpiece M, (that may be made angular. or cylindrical,)

is then tbrmed into pipe or pipes, a-nd as the clay-pipe passes from the mouth-piecel it is supported by a self-I acting platform, N, beneath which lowers, by the weight of the pipe, as the pipe lengthens, until the .p it'orm reaches its properooring, thatis tixed at the d tance that the length ofthe pipe is intended or required to be, when the pipe is eut oti, by a wire or otherwise, at tbc end oi'tbe. mouth-piece, and removed by the movable plate P, that has held the end of the pipe steadily by its circular ring or rings 1t,

correspoudiug wit-li la single pipe, or any number of diti'erent sized pipes, the plattbrlu N being regulated by its ropes and weights, S, that raise it.

The mouth-'piece M is permanently held to the bottom of the hopper (1i by two adjustable turn-buckles, T, and permanent pins, u il, that centre the mouthpiece. to its proper position.

When l desire to make various sizes of pipes, I have the moutlpiece M formed of two or more cylinders, as shown at tig. 3, and when I wish to make four pipes at one operation, I form the mouth-piece as shown at iig. 4.

In ibrming the gutter-pieces,] divide each cylinder, by inserting a cross-piece, V, at the bottoni ofthe mouth-piece, and inl fiwming' the curb and gutterpiece, l shape and construct the mouth-piece with or without a projecting flange, W, at either or both ends ot' the opening X, as shown at iig. (i.

I do not claim, as new, the several devices above described, nor any general combination ot' the saine; but

What I claim,- and desire to secure by Letters Patent of the United States. is-

The improved arrangement, in the drain-tile machine above described, of the parts herein shown, consisting of the vertical tapering clay-hopper or pngmill G, with its flanges H, ringr K, grooves L, the

vertical shaft C, with anged screw D, tlanges I, i

grooved tapering screw E, and removable mouthpiece M, when said parts are all constructed, arranged, and operating as herein described, and for the purposes set forth.

I. C. BRYANT.
